Serhiy Storchaka added the comment:
The phrase "*function* should return either a string or a tuple containing two or three elements." de-facto is outdated too. Since Python 2.3 a tuple returned by the function must have two to five elements.
copyreg.constructor() no longer does anything useful, and the constructor parameter of copyreg.pickle() is virtually ignored.
